CDE Infrastructure

The programming infrastructure, not the productivity tools, forms the major strength of the Common Desktop Environment. This article discusses the APIs and desktop services that benefit developers and independent software vendors.
ToolTalk Server

The ToolTalk server can be relied upon to broker client and server messages for inter-client plug-and-play. The common object request broker architecture (CORBA) movement has a great deal of strength behind it. But ToolTalk is lightweight, does the job and forms an integral part of CDE, which is deployed across a gamut of Unix platforms. ToolTalk takes message-handling registrations from method servers, then holds that information until client applications broadcast for those registered services. Platform gateways are not needed because ToolTalk interoperates between heterogeneous systems.

Go For It

There is much more to CDE than meets the eye. Application and workspace developers alike have a rich feature-filled infrastructure upon which to build. Just like in the past, we still rely on the tried and true X and Motif; however, now we can count on the Common Desktop Environment for its development libraries and desktop management infrastructure.

If you are getting ready to write a new application or just thinking about sprucing up something that you have been working on, consider how your application can become more feature rich and desktop friendly with less code.

Linux Management with Red Hat Satellite: Measuring Business Impact and ROI

Linux has become a key foundation for supporting today's rapidly growing IT environments. Linux is being used to deploy business applications and databases, trading on its reputation as a low-cost operating environment. For many IT organizations, Linux is a mainstay for deploying Web servers and has evolved from handling basic file, print, and utility workloads to running mission-critical applications and databases, physically, virtually, and in the cloud. As Linux grows in importance in terms of value to the business, managing Linux environments to high standards of service quality — availability, security, and performance — becomes an essential requirement for business success.

White Paper
Private PaaS for the Agile Enterprise

If you already use virtualized infrastructure, you are well on your way to leveraging the power of the cloud. Virtualization offers the promise of limitless resources, but how do you manage that scalability when your DevOps team doesn’t scale? In today’s hypercompetitive markets, fast results can make a difference between leading the pack vs. obsolescence. Organizations need more benefits from cloud computing than just raw resources. They need agility, flexibility, convenience, ROI, and control.

Stackato private Platform-as-a-Service technology from ActiveState extends your private cloud infrastructure by creating a private PaaS to provide on-demand availability, flexibility, control, and ultimately, faster time-to-market for your enterprise.
